Ch 1: Introduction to Human Biology

About This Chapter

The Introduction to Human Biology chapter of this Human Biology Study Guide course is the simplest way to master introductory material on human biology. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure you learn the essentials of human biology.

Who's It For?

Anyone who needs help learning or mastering introductory material on human biology will benefit from the lessons in this chapter. There is no faster or easier way to learn about human biology. Among those who would benefit are:

  • Students who have fallen behind in understanding anatomical directional terminology or the planes of the human body
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning biology (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about human biology
  • Students who struggle to understand their teachers
  • Students who attend schools without extra biology learning resources

How It Works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Introduction to Human Biology chapter exam.

Why It Works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the Introduction to Human Biology chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any question on human biology. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students Will Review:

This chapter helps students review the concepts in an introduction to human biology unit of a standard human biology course. Topics covered include:

  • Human evolution and the human fossil record
  • Evolutionary history
  • Multicellular organisms
  • The anatomy and planes of the human body
  • Anterior, posterior, lateral, medial and other locational terminology
  • The human hands, limbs and feet

The Human Fossil Record & Human Evolution

1. The Human Fossil Record & Human Evolution

Fossils can help tell the story of how we evolved. This lesson sheds light on our closest relatives from the past and what traits human beings have developed over time. You'll learn about those species that are extinct but who live on in our genes.

The Evolution of Humans: Characteristics & Evolutionary History

2. The Evolution of Humans: Characteristics & Evolutionary History

Just like other organisms, humans have changed over time. We will look at the evolution of humans as well as connections with our primate relatives, including Old World and New World primates.

Multicellular Organisms, Tissues and Epithelium

3. Multicellular Organisms, Tissues and Epithelium

In this lesson on multicellular organisms, you'll take a look at what it actually means to be multicellular and how cells are organized into tissues, organs, and organ systems. This lesson also covers one of the four main tissue types: epithelial tissue.

Planes of the Human Body: Definition, Anatomy & Diagram

4. Planes of the Human Body: Definition, Anatomy & Diagram

Learn about the different ways in which your body can be divided or cut up for theoretical and practical purposes as we explore the sagittal plane, transverse plane and coronal plane.

Anatomical Directional Terminology: Anterior, Posterior and More

5. Anatomical Directional Terminology: Anterior, Posterior and More

Find out how to properly refer to the location of things at the front and back of a person as well as above or below a certain point on the body by learning the terms anterior, posterior, superior, and inferior.

Anatomical Directional Terminology: Lateral, Medial & More

6. Anatomical Directional Terminology: Lateral, Medial & More

Learn what it means to be on the same side as something else or on a different side altogether. In addition, find out what it means to be closer to or farther away from the middle of something as we explore the following terms: lateral, medial, ipsilateral, and contralateral.

Anatomical Directional Terminology: Limbs, Hands & Feet

7. Anatomical Directional Terminology: Limbs, Hands & Feet

In this lesson, you'll learn how we term the different sides of our feet and hands thanks to words like dorsal, plantar and palmar. You'll also learn how we name something that is near or far away from the trunk of our body thanks to words like proximal and distal.

What Is Homeostasis? - Definition & Examples

8. What Is Homeostasis? - Definition & Examples

Homeostasis can be defined as a property of an organism or system that helps it maintain its parameters within a normal range of values. It is key to life, and failures in homeostasis can lead to diseases like hypertension and diabetes.

What is Melanin? - Definition, Production & Function

9. What is Melanin? - Definition, Production & Function

Melanin is a pigment produced in the skin of almost all animals on Earth. Its role in animal survival is critical, and varies depending on the organism. This article addresses melanin function and expression in humans and other organisms, and its role in survival.

What is Biological Anthropology? - Definition & Subfields

10. What is Biological Anthropology? - Definition & Subfields

Why do some people fear open spaces? How can science help solve crimes? These and many other questions have much to do with the field of biological anthropology.

Harvey Cushing: Biography, Inventions & Quotes

11. Harvey Cushing: Biography, Inventions & Quotes

In this lesson, we will discuss the life of the Founding Father of Neurosurgery, Dr. Harvey Cushing. We will also look at some of his career accomplishments, medical inventions and some of the more famous aspects that Dr. Cushing is known for.

Influences on Health: Social, Cultural & Environmental

12. Influences on Health: Social, Cultural & Environmental

Have you ever noticed that even though you have a healthy lifestyle, sometimes your surroundings have a big effect on your health outcomes? Learn about how social norms, cultural beliefs, and environmental conditions can impact our health.

Body Burden: Definition, Chemicals & Testing

13. Body Burden: Definition, Chemicals & Testing

The amount of toxic chemicals and pollutants that have settled in a human body over the course of a lifetime is known as the body burden. This lesson is about body burden, the chemicals found, and the testing that is done.

Dorsal Body Cavity: Definition, Organs & Membranes

14. Dorsal Body Cavity: Definition, Organs & Membranes

The dorsal cavity of the body is simpler than the ventral, but still detailed. We will discuss the dorsal cavity by looking at the organs, divisions, and membranes that make up this cavity.

Ventral Body Cavity: Definition, Subdivisions & Organs

15. Ventral Body Cavity: Definition, Subdivisions & Organs

Studying the body can be very overwhelming when it is viewed as a whole. This lesson zooms in a bit to focus on the ventral cavity, its divisions, subdivisions, and the organs it contains.

Biosemiotics: Definition & Overview

16. Biosemiotics: Definition & Overview

All living things have the ability to communicate with each other using a variety of signs and signals. In this lesson, learn all about biosemiotics, which is the study of all the ways that organisms communicate with each other.
